“We could have had it all.” Well, at this point, Adele you sort of do have it all.

In addition to her Grammys sweep last night (the acclaimed songstress won in all six of her nominated categories, including Record of the Year for “Rolling in the Deep” and Album of the Year for her platinum smash 21), Adele is once again dominating the charts. As of Monday, the Grammy-winning 21 (which has spent fifty weeks on Billboard) topped the iTunes charts, just ahead of Whitney Houston‘s Greatest Hits album. The late singer’s catalog unsurprisingly saw a surge in sales over the weekend after the news of her passing. But Adele (whose previous Grammy-winning album 19 also found its way into the top 10) wasn’t the only one to get an iTunes boost. Coldplay, the Civil Wars, and Kelly Clarkson also saw a boost thanks to their Grammy appearances.

But over on Amazon.com’s Best Sellers list, it was once again, overwhelmingly Adele and Houston. While 21 currently sits at the No. 1 spot and 19 at No.5, ten of the top twenty belong to Houston, including The Greatest Hits (No. 2) The Ultimate Collection (No. 3), and the record-breaking soundtrack The Bodyguard (No. 4). It will be fascinating to see how these two particular albums (The Bodyguard and 21) play out in the coming weeks and which one will claim the title for having their record be all-time at No. 1. Either way, it’s a stirring testament to how a great, timeless female voice has its place in music history.
